BL Shanghai Belling · Relay / Coil Drivers · SOP-8

BL8023C from BL Shanghai Belling, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OA output Output A, relay driver output capable of 300mA typical driving current, logic state determined by inputs A and B according to logic function table.
2 NC unconnected Not connected to internal circuit.
3 A input Input A, active high with 3V threshold, input rise/fall time must be less than 1ms to prevent device damage.
4 GND power_in Ground, reference potential for device operation.
5 OB output Output B, relay driver output capable of 300mA typical driving current, logic state inverted relative to output A.
6 NC unconnected Not connected to internal circuit.
7 B input Input B, active high with 3V threshold, input rise/fall time must be less than 1ms to prevent device damage.
8 VIN power_in Supply voltage input, 5V to 36V operating range recommended, 40V absolute maximum, quiescent current 1μA typical.
